0:00:02 > 0:00:03It's a brand-new term
0:00:03 > 0:00:06and CBBC have sent these four magicians back to school.
0:00:06 > 0:00:09They're pretending to be supply teachers,
0:00:09 > 0:00:14so that they can perform amazing magic on unsuspecting classes.
0:00:14 > 0:00:16But because you know and love them,
0:00:16 > 0:00:18this time, we've cunningly disguised them.
0:00:21 > 0:00:25Then we hid secret cameras all over classrooms
0:00:25 > 0:00:28and watched as they taught spectacular lessons.
0:00:28 > 0:00:31Well, it's flying around, like a magic saucer.
0:00:31 > 0:00:33CHILDREN SHOUT AND CHEER
0:00:33 > 0:00:35That was sick!
0:00:35 > 0:00:39It's more magic, it's more outrageous!
0:00:39 > 0:00:40I was just flabbergasted.
0:00:40 > 0:00:43But how long will it take before the classes shout...
0:00:47 > 0:00:50CHILDREN CHEER
0:00:50 > 0:00:53Hello! It's me, Iain, we're back to school for a new term -
0:00:53 > 0:00:58it's Help! My Supply Teacher Is STILL Magic. You could say it's...
0:00:58 > 0:01:00- DEEP VOICE:- Help! My Supply Teacher Is Magic 2:
0:01:00 > 0:01:03The Lord Of The Disappearing Rings.
0:01:03 > 0:01:07- NORMAL VOICE:- Once again, we swapped regular teachers with magicians
0:01:07 > 0:01:09and, because you know them, we've disguised them.
0:01:09 > 0:01:12We filmed the results with special cameras hidden in the classrooms.
0:01:12 > 0:01:15Yeah! We're cleverer than a boomerang
0:01:15 > 0:01:17with a round-the-world air ticket.
0:01:17 > 0:01:21We're also showing you loads of other great tricks. Like this.
0:01:21 > 0:01:25Watch as I carefully produce a coin from behind my ear.
0:01:27 > 0:01:31Eh?! I always keep one spare. Here's the clips.
0:01:32 > 0:01:35Katherine lightens up this lesson with a shadowy trick
0:01:35 > 0:01:37and a surprise with zip.
0:01:37 > 0:01:39Look, it's Fergus!
0:01:39 > 0:01:44You'll need any 15 playing cards or trading cards
0:01:44 > 0:01:47to play along with Fergus's interactive illusion.
0:01:48 > 0:01:51Plus you've been sending in clips of all your best magic tricks.
0:01:51 > 0:01:54And later on, I'll be picking my favourite.
0:01:54 > 0:01:57The Wannabe Wizards are the business, but first...
0:01:59 > 0:02:03Do you think you'd be able to tell if your teacher started doing magic?
0:02:03 > 0:02:04Do you?
0:02:06 > 0:02:10This is Katherine. She's a cunning conjurer who loves surprises.
0:02:12 > 0:02:14She's dressed for the great outdoors,
0:02:14 > 0:02:18but she's come in from the cold and the class are in for a treat.
0:02:18 > 0:02:20- BELL RINGS - Enter Year Four.
0:02:20 > 0:02:21They don't know it yet,
0:02:21 > 0:02:24but Katherine's about to give them a lesson about camping,
0:02:24 > 0:02:27where the magic is "in tents"!
0:02:27 > 0:02:30None of them have recognised Katherine in her wig and wellies,
0:02:30 > 0:02:33or noticed the hidden cameras in their school hall.
0:02:33 > 0:02:36When the magic begins, will the class fill their boots?
0:02:36 > 0:02:40Now, I'm here from Millsy's Adventures.
0:02:40 > 0:02:42Now, this is a scheme
0:02:42 > 0:02:46that promotes fun, adventurous outdoor activities.
0:02:46 > 0:02:50Little do they know, the activity Katherine's got planned is magic.
0:02:50 > 0:02:54So, I've brought with me one of the tents that we use.
0:02:54 > 0:02:59So I'm just going to turn it round, so it's the right way round,
0:02:59 > 0:03:04facing you all. Now, this here is the smallest tent that we do.
0:03:04 > 0:03:08It fits two people. I'm going to show you what it looks like inside.
0:03:08 > 0:03:10That zip's a bit tricky, but no magic yet.
0:03:10 > 0:03:14So if we open up the tent, you can all see inside.
0:03:14 > 0:03:19- Now, it's pretty cosy, but does fit two people.- And note, it's empty.
0:03:19 > 0:03:22OK, so sometimes when you're camping, it is quite tight.
0:03:22 > 0:03:24But we'll do that up again...
0:03:24 > 0:03:26ZIP SQUEAKS
0:03:26 > 0:03:28..like this. Now...
0:03:28 > 0:03:32the most important thing when you're camping is to be prepared.
0:03:32 > 0:03:35So can any of you have a think about what kind of things
0:03:35 > 0:03:38you might want to take when camping? Any ideas? Yes?
0:03:38 > 0:03:42- A torch?- A torch? Brilliant! I've actually got a torch here.
0:03:42 > 0:03:46Here we go. So we've got our torch. Very good. Yes?
0:03:46 > 0:03:48Sleeping bag?
0:03:48 > 0:03:52A sleeping bag? Brilliant, well done! Yes, a sleeping bag.
0:03:52 > 0:03:56Now, a sleeping bag keeps you nice and warm.
0:03:56 > 0:03:58So we'll put our sleeping bag down there.
0:03:58 > 0:04:02I'll show you some other things you might want to take. A camping mat.
0:04:02 > 0:04:04Not only can you use it while you're eating,
0:04:04 > 0:04:07you can sit down and have a picnic on it, it's a great thing, you can
0:04:07 > 0:04:10also put your sleeping bag on top of it, so it's more comfortable.
0:04:10 > 0:04:12With her camping mat, Katherine's pulled the wool
0:04:12 > 0:04:15over the class's eyes. They don't suspect a thing!
0:04:15 > 0:04:19Now, one of my favourite things to do when camping
0:04:19 > 0:04:23is to sit round the fire telling stories and playing games.
0:04:23 > 0:04:27Now, one of my favourite games is a game called shadows.
0:04:27 > 0:04:29You make shadows on the tent with your hands
0:04:29 > 0:04:32and everyone guesses what shape you're trying to make.
0:04:32 > 0:04:35And I thought it'd be great fun if we had a go at playing that now.
0:04:35 > 0:04:37Year Four are still in the dark,
0:04:37 > 0:04:40but will Katherine's shadowy story make them suspect soon?
0:04:40 > 0:04:44All I'm going to do is just
0:04:44 > 0:04:48place this light into the tent, like that,
0:04:48 > 0:04:51and we're going to use our torch
0:04:51 > 0:04:55to light my hands up while making the shadows.
0:04:55 > 0:04:59So we can all see the torch shining the light there.
0:04:59 > 0:05:01So are you ready to play the game, everyone?
0:05:01 > 0:05:03- ALL:- Yeah! - Yeah? Brilliant, OK!
0:05:03 > 0:05:06So my first shadow shape is this.
0:05:06 > 0:05:09Let's see if you can guess what it is.
0:05:09 > 0:05:10You can shout out.
0:05:10 > 0:05:12- Bird!- Butterfly!
0:05:12 > 0:05:15- A bird!- Good shadow of a bird. Standard stuff.
0:05:15 > 0:05:23OK, so let's try another one, OK? So what do you think this one is?
0:05:23 > 0:05:25What do you think it is? You can shout out.
0:05:25 > 0:05:28- Rabbit!- It's a rabbit! Well done!
0:05:28 > 0:05:29That rabbit's good!
0:05:29 > 0:05:32OK, now, this one is definitely a lot trickier.
0:05:32 > 0:05:35See if you can get this one. Are you ready?
0:05:35 > 0:05:37Let's have a go.
0:05:37 > 0:05:38- A tree!- It's a tree!
0:05:38 > 0:05:42Her hands can't be making that, surely? She's having a giraffe!
0:05:42 > 0:05:43I mean, a laugh.
0:05:43 > 0:05:45Gosh, you're good at this game!
0:05:45 > 0:05:47Now this next one I'm going to show you
0:05:47 > 0:05:50is something I've been working on for a long, long time.
0:05:50 > 0:05:52Let's see.
0:05:52 > 0:05:53A house!
0:05:53 > 0:05:57That's incredible! And impossible! And magic!
0:05:57 > 0:05:59You can't do that with just your hands!
0:05:59 > 0:06:01Brilliant! Well done, everyone!
0:06:01 > 0:06:03They are literally open-mouthed.
0:06:03 > 0:06:07If they were out camping, they'd be catching flies.
0:06:07 > 0:06:12Now, we've spoken a lot about being prepared when camping,
0:06:12 > 0:06:14which is obviously really, really important,
0:06:14 > 0:06:17but there is something that's even more important than that.
0:06:17 > 0:06:20I wonder if they're prepared for some even better magic?
0:06:20 > 0:06:24It's really important that you have somebody with you when camping.
0:06:24 > 0:06:27I always take a friend of mine with me when I'm camping.
0:06:27 > 0:06:28He's very experienced.
0:06:28 > 0:06:30He knows what he's doing,
0:06:30 > 0:06:32and he can turn up anywhere.
0:06:32 > 0:06:35I know he's always, always going to be there.
0:06:36 > 0:06:38CHILDREN GASP
0:06:38 > 0:06:40And here he is! Look, it's Fergus!
0:06:40 > 0:06:43They weren't ready for that! The tent looked empty.
0:06:43 > 0:06:47That's amazing, and it's time to uncover the truth.
0:06:47 > 0:06:48We are magicians, and you're all
0:06:48 > 0:06:51being filmed right now to be on Help! My Supply Teacher Is Magic!
0:06:58 > 0:07:00The class didn't see that one coming.
0:07:00 > 0:07:03But when we canvassed opinion on the tent trick,
0:07:03 > 0:07:05how did they describe it?
0:07:05 > 0:07:07Wow! Shocking!
0:07:07 > 0:07:09It was really amazing.
0:07:09 > 0:07:14- Let's see...- Katherine's magical shadows were illuminating.
0:07:14 > 0:07:18I wasn't sure how she'd make a house doing that,
0:07:18 > 0:07:23because the tree, it was like, it looked really realistic.
0:07:23 > 0:07:25Let's have a go.
0:07:25 > 0:07:28Up sprouted a shadowy tree and out sprung a beaming Fergus!
0:07:28 > 0:07:30Look, it's Fergus!
0:07:30 > 0:07:36I was like, how would he get in there without being seen?
0:07:36 > 0:07:41I always have wanted to be on Help! My Supply Teacher Is Magic
0:07:41 > 0:07:43and it's quite amazing.
0:07:43 > 0:07:47You are on it! It was amazing!
0:07:47 > 0:07:51And the class had no idea Katherine was a magician!
0:07:51 > 0:07:53How long would it take for you to shout...
0:08:01 > 0:08:02Later on, you'll see what happened
0:08:02 > 0:08:05when John went undercover at another school.
0:08:05 > 0:08:09He's going to bamboozle them with some mathe-magic.
0:08:09 > 0:08:11I think that's pretty clear how it's worked.
0:08:11 > 0:08:15Now it's James, with a mind-blowing trick, Up Close And Magical.
0:08:15 > 0:08:17So in time-honoured tradition,
0:08:17 > 0:08:20I'd like you to pick a card, any card.
0:08:20 > 0:08:23You sure? Not that one, please not that one.
0:08:23 > 0:08:25OK, you can pick that one, I don't mind. So can you see it?
0:08:25 > 0:08:27OK, what I'd like to do, Daniel,
0:08:27 > 0:08:30is write your name nice and big on the face of the card,
0:08:30 > 0:08:32and make sure the cameras can see you.
0:08:32 > 0:08:34I'm going to turn around so I don't cheat.
0:08:36 > 0:08:39- Remember, Daniel's written his name on the six of spades.- Done it.
0:08:39 > 0:08:42Done it? I'll just get that cap back.
0:08:42 > 0:08:44So we can pop that cap back on there.
0:08:44 > 0:08:47Pop that in the pocket. Now, we're going to lose your card in the deck,
0:08:47 > 0:08:50so I take your card, put it about halfway down.
0:08:50 > 0:08:53- James doesn't know what the card is. - This is where the magic happens.
0:08:53 > 0:08:56- Are you ready? Are you ready?- Yes. - Am I ready? I think I'm ready.
0:08:56 > 0:08:58- Obviously you're ready! - I'm ready, OK. Watch.
0:08:58 > 0:09:01If I snap, one card comes to the top of the deck,
0:09:01 > 0:09:03the Joker. Was that your card?
0:09:03 > 0:09:05- No.- No.
0:09:07 > 0:09:09- The Joker was your card.- No.
0:09:09 > 0:09:12Fine. OK, have it your way, that's fine.
0:09:12 > 0:09:15- Don't worry, nobody noticed. Move on.- We'll try something else.
0:09:15 > 0:09:17If I take these, OK,
0:09:17 > 0:09:19Ebony, can you hold onto these? These are some balloons.
0:09:19 > 0:09:21Daniel, take any balloon you want.
0:09:21 > 0:09:24That's it, the magic's not working, try balloon modelling.
0:09:24 > 0:09:27So we have a balloon and a deck of cards,
0:09:27 > 0:09:30so balloon, deck of cards, balloon, deck of cards.
0:09:30 > 0:09:32Watch, on three. One, two, three...
0:09:34 > 0:09:36Deck of cards goes inside the balloon.
0:09:36 > 0:09:40- Look, it's actually in there.- No way! The deck's inside the balloon!
0:09:40 > 0:09:43But that's only half the trick. In fact, we don't need those any more.
0:09:43 > 0:09:47We can get rid of the rest of the balloons! That's only half the trick.
0:09:47 > 0:09:50The other half - I've still got to find your card,
0:09:50 > 0:09:53which is more difficult now because they're in a balloon! Watch.
0:09:57 > 0:10:00I'll just give them a little shuffle. I think I can see it.
0:10:00 > 0:10:04- What's he doing?- I'm going to reach in, pull one card out...
0:10:05 > 0:10:10..of the balloon, which is your signed six of spades,
0:10:10 > 0:10:12and there is a deck of cards in a balloon.
0:10:12 > 0:10:14Eh? That's just balloony.
0:10:14 > 0:10:16Give it a shake.
0:10:16 > 0:10:19OK, try and get another one out. No, it doesn't work.
0:10:19 > 0:10:21- Got a pin?- No!
0:10:21 > 0:10:24Only trained magicians can do it! Nice one, dude!
0:10:24 > 0:10:27Look, he just had a balloon in his hand and he had the cards,
0:10:27 > 0:10:30and put it on top. Bam! It's in!
0:10:31 > 0:10:33No, you don't do that!
0:10:33 > 0:10:36- It's not normal to do that! - Then he pulled the card out.
0:10:36 > 0:10:38And there's the card.
0:10:38 > 0:10:39He takes a card out of the balloon -
0:10:39 > 0:10:42serious! That don't happen in real life!
0:10:42 > 0:10:45It's like, if I tried, if I tried it right now,
0:10:45 > 0:10:50it ain't going to happen! It's like, it ain't going to happen!
0:10:50 > 0:10:53It's time for Katherine to set you a magical challenge
0:10:53 > 0:10:54in Tricks Of The Trade.
0:10:54 > 0:10:56If you fancy yourself as a magician,
0:10:56 > 0:10:59here's a trick you can try on your mates.
0:10:59 > 0:11:01Katherine's got a piece of paper,
0:11:01 > 0:11:03a pen and also a mirror.
0:11:03 > 0:11:07She's going to show you how to write a word on a piece of paper
0:11:07 > 0:11:10that looks exactly the same when it's put in front of a mirror.
0:11:12 > 0:11:13Give it a go, Katherine.
0:11:13 > 0:11:15It can't be done, can it?
0:11:15 > 0:11:17Can you work out how to do it?
0:11:17 > 0:11:20Keep watching and you'll find out later in the show.
0:11:20 > 0:11:22It's going to be incredible.
0:11:24 > 0:11:27Right now, we have something amazing for you.
0:11:27 > 0:11:29This is the Interactive Illusion.
0:11:29 > 0:11:32This is a trick where you can take part at home,
0:11:32 > 0:11:34so come on, you need to pay close attention,
0:11:34 > 0:11:36so get over here, come on, don't be shy.
0:11:36 > 0:11:39I think Fergus is wearing his new aftershave,
0:11:39 > 0:11:42even though it looks like he hasn't had a shave. Weird.
0:11:44 > 0:11:48Remember, you'll need just 15 cards, so get them ready.
0:11:48 > 0:11:51We're going to do a card trick, but we'll use your cards.
0:11:51 > 0:11:56You can use playing cards or trading cards. It doesn't really matter.
0:11:56 > 0:11:59As long as all the cards are different, the trick will work.
0:11:59 > 0:12:01We won't need the whole deck.
0:12:01 > 0:12:02We only need 15 cards,
0:12:02 > 0:12:07so take them out now and then leave the rest to one side.
0:12:07 > 0:12:11Take those 15 cards in a packet and hold them face up.
0:12:11 > 0:12:16I want you to deal the cards into three face-up piles,
0:12:16 > 0:12:17just like this.
0:12:18 > 0:12:23You want to carry on going until all the cards in your hand are gone.
0:12:24 > 0:12:27That will leave you with three equal packets.
0:12:27 > 0:12:30Now I want you to pick up any one of those packets.
0:12:30 > 0:12:32I'm going to choose this one,
0:12:32 > 0:12:34but you can choose any one you like.
0:12:34 > 0:12:39And then, spread those cards so you can see all of them.
0:12:39 > 0:12:42What I want you to do now is to remember a card,
0:12:42 > 0:12:46so commit it to memory and don't forget it.
0:12:46 > 0:12:48I'm going to remember the four of diamonds,
0:12:48 > 0:12:51but I'm sure yours is different.
0:12:51 > 0:12:55Without changing the order of the cards, push them back together
0:12:55 > 0:12:59and place them on either one of the packets on the table.
0:12:59 > 0:13:01I'm going to place mine there
0:13:01 > 0:13:03and then pick up the other packet
0:13:03 > 0:13:06and place that on the two. Fantastic job.
0:13:06 > 0:13:11Now, there is no way I could know which card you are thinking of,
0:13:11 > 0:13:14but to make this even more difficult,
0:13:14 > 0:13:16I want you to pick up that packet
0:13:16 > 0:13:20and deal it out into three piles just like before.
0:13:20 > 0:13:22Do that with me now.
0:13:23 > 0:13:25And again, you'll carry on going
0:13:25 > 0:13:29until all the cards in your hand are gone.
0:13:29 > 0:13:32Fantastic. Look through the cards on the table
0:13:32 > 0:13:35and pick up the pile that contains your card,
0:13:35 > 0:13:37so my one's here.
0:13:37 > 0:13:41Find yours now, and once you've got that pile,
0:13:41 > 0:13:44drop it on one of the two other packets.
0:13:44 > 0:13:46Pick up the final packet,
0:13:46 > 0:13:48and place that on top of everything.
0:13:48 > 0:13:52Now, you need to make a very important choice.
0:13:52 > 0:13:55You can hold the packet face up like you have been,
0:13:55 > 0:13:58or you can turn it face down, like this.
0:13:58 > 0:14:02The choice is yours, but do that for me now.
0:14:02 > 0:14:05OK. Don't move the cards.
0:14:05 > 0:14:08I'm going to make a prediction.
0:14:08 > 0:14:12My prediction is the number eight.
0:14:13 > 0:14:15Slowly deal the cards down onto the table,
0:14:15 > 0:14:17and the eighth card will be yours.
0:14:17 > 0:14:20One, two,
0:14:20 > 0:14:25three, four, five, six, seven...
0:14:27 > 0:14:28..eight. Did you get yours?
0:14:30 > 0:14:32Did it work for you?
0:14:32 > 0:14:34Wow. Well, the quantity of the magic is exhausting
0:14:34 > 0:14:38and the quality has been electrifying. In fact,
0:14:38 > 0:14:40I'm basically a ball of static,
0:14:40 > 0:14:43so I feel like I've earned a sit-down.
0:14:43 > 0:14:45Oh! Before that, let's have a look at what's coming up.
0:14:45 > 0:14:47It's all kinds of ridiculousness.
0:14:49 > 0:14:52James gets up close and magical with mind-reading cubed.
0:14:54 > 0:14:57Katherine reveals a secret in Tricks Of The Trade.
0:14:57 > 0:14:58Have you worked it out yet?
0:14:58 > 0:15:02And watch what happens when John goes undercover in another school.
0:15:02 > 0:15:04Will he fool the class
0:15:04 > 0:15:07or will they realise their supply teacher is still magic?
0:15:09 > 0:15:11Ooh! Each week,
0:15:11 > 0:15:14I'm bringing you another of my new favourite magic movers and shakers
0:15:14 > 0:15:17doing tricks in their own cribs, yards and front rooms.
0:15:17 > 0:15:20We call them the Wannabe Wizards,
0:15:20 > 0:15:22so I've got my comfy chair,
0:15:22 > 0:15:24I've got some fortune cookies,
0:15:24 > 0:15:27and I've got my computer to watch all the magic on. Amazing.
0:15:30 > 0:15:33"Amazing magic you will see"?
0:15:33 > 0:15:35Who wrote that, Yoda? Hit it.
0:15:37 > 0:15:40We asked you to send in clips of yourself performing your best
0:15:40 > 0:15:44magic tricks. We received loads of clips from all over the country.
0:15:44 > 0:15:47Each episode, I'll be choosing a favourite Wannabe Wizard
0:15:47 > 0:15:49and showing them to you guys.
0:15:49 > 0:15:51My Wannabe Wizard this time is William from Bristol,
0:15:51 > 0:15:55and he's got a card trick with an extremely tricky card.
0:15:56 > 0:15:58I'm going to show you a card trick.
0:15:58 > 0:16:01So, just pick a card,
0:16:01 > 0:16:02any card that you'd like.
0:16:05 > 0:16:09It's the three of diamonds. Thanks, random hand!
0:16:09 > 0:16:12Three of diamonds, what a surprise.
0:16:12 > 0:16:15Well, not really. This card is a bit of a pest, to be honest.
0:16:15 > 0:16:18It always wants to get picked and it always does get picked.
0:16:18 > 0:16:21Very annoying. I'll show you how much of a pest it really is.
0:16:21 > 0:16:23If I get the three of diamonds
0:16:23 > 0:16:24and then just push it in like that,
0:16:24 > 0:16:27it always jumps out at me.
0:16:27 > 0:16:31See, like that, saying, "Pick me, pick me!" The three of diamonds.
0:16:31 > 0:16:33That card sure is pesky!
0:16:33 > 0:16:36Even though I try to be crafty with it,
0:16:36 > 0:16:39and I put it in the middle
0:16:39 > 0:16:44and I try and randomly catch a different card out of the middle,
0:16:44 > 0:16:46it still doesn't work.
0:16:46 > 0:16:48Such a pest, that card!
0:16:48 > 0:16:50Let's get a rewind!
0:16:50 > 0:16:53Whoa! He just can't shake that card
0:16:53 > 0:16:56and we can't forget William, our Wannabe Wizard.
0:16:56 > 0:16:59Now it's time for Katherine to reveal the secret
0:16:59 > 0:17:01in Tricks Of The Trade.
0:17:02 > 0:17:05Katherine will show you how to write a word on a piece of paper
0:17:05 > 0:17:08that looks exactly the same when it's put in front of a mirror.
0:17:08 > 0:17:12Come on, have you worked it out? How many of you got it?
0:17:12 > 0:17:14Did you use a different alphabet?
0:17:14 > 0:17:16Nah!
0:17:16 > 0:17:18Is it a trick mirror?
0:17:18 > 0:17:20Don't be silly!
0:17:20 > 0:17:25The trick is that only nine magical letters will work. They are...
0:17:29 > 0:17:32When you put these letters in front of a mirror,
0:17:32 > 0:17:35facing away from the mirror, they look the same. See?
0:17:35 > 0:17:38As long as your words have these magical letters in them,
0:17:38 > 0:17:41the trick will work. Here's some of Katherine's favourite magical words.
0:17:41 > 0:17:43Dice, good one.
0:17:43 > 0:17:46Hide, that's another nice one there.
0:17:46 > 0:17:48And now you've cracked the code,
0:17:48 > 0:17:52you've got something to show off with in the playground.
0:17:52 > 0:17:54Next, to my mind, the best mind-reader.
0:17:54 > 0:17:57It's James, Up Close And Magical.
0:17:57 > 0:18:02I'd love to show you this amazing trick with my keyring, OK?
0:18:02 > 0:18:05But before I do that, Libby,
0:18:05 > 0:18:07if you could hold onto that wallet for me?
0:18:07 > 0:18:10- That'll be important in a bit. - Remember the wallet.
0:18:10 > 0:18:12I've got this keyring.
0:18:12 > 0:18:14It's like a miniature Rubik's Cube,
0:18:14 > 0:18:19and you can see there's lots of colours. There's green, red, yellow.
0:18:20 > 0:18:24Charlie, what I'd like you to do is pick one of these colours,
0:18:24 > 0:18:27put it on your hand, so it's facing upwards,
0:18:27 > 0:18:30and then put your other hand on top so nobody can see what colour it is.
0:18:30 > 0:18:32And I'm going to turn my back while you do that.
0:18:32 > 0:18:34Choose carefully, Charlie.
0:18:34 > 0:18:36James is going to try and read your mind.
0:18:37 > 0:18:40- Done?- Yeah.
0:18:40 > 0:18:44OK, I'm going to try and guess which colour you've gone for, OK? So...
0:18:45 > 0:18:49I think you're going to make this easy. I think you've gone for red.
0:18:49 > 0:18:51You're done red? Wow!
0:18:51 > 0:18:53But maybe you just think that was a lucky guess,
0:18:53 > 0:18:55because there's only six colours.
0:18:55 > 0:19:00This time, what I want you to do is move the cube around in your hand,
0:19:00 > 0:19:02so even you don't know what colour it is, OK?
0:19:02 > 0:19:04And I'm going to turn my back.
0:19:08 > 0:19:10- Done that?- Yeah.
0:19:13 > 0:19:15OK, let's see. Do you know what the colour is?
0:19:17 > 0:19:19This is tough, this is tough.
0:19:23 > 0:19:26Yeah, I think this time it's green.
0:19:26 > 0:19:28It is green! Amazing!
0:19:28 > 0:19:32Two out of three! OK, so maybe that was just a lucky guess,
0:19:32 > 0:19:36but what if I could predict the next colour you were going to pick?
0:19:36 > 0:19:38- That would be amazing, wouldn't it?- Yeah.
0:19:38 > 0:19:42OK, think of any colour on that cube you want, it doesn't matter if I see,
0:19:42 > 0:19:45and just turn it to whichever colour you want.
0:19:46 > 0:19:49Yellow? You sure?
0:19:49 > 0:19:52Want to change your mind? Give you two seconds.
0:19:52 > 0:19:54He's going to change his mind! Ooh, tricky!
0:19:54 > 0:19:57- Orange. Are you sure you want to stick with orange?- Yeah.
0:19:57 > 0:19:59You were quite dead set on yellow there,
0:19:59 > 0:20:01but now you've gone for orange.
0:20:01 > 0:20:04- OK, Libby, I gave you a wallet right at the beginning.- You did.
0:20:04 > 0:20:06Can I just take that? Now, this is interesting
0:20:06 > 0:20:10because inside my wallet, there is one business card,
0:20:10 > 0:20:13with "Help! My Supply Teacher Is Magic" on the back.
0:20:15 > 0:20:17On the front is the name of a colour...
0:20:19 > 0:20:21..which I wrote down earlier.
0:20:21 > 0:20:24You could have had any colour, and you went for orange.
0:20:26 > 0:20:29And the card says, "Orange"!
0:20:29 > 0:20:30He predicted orange!
0:20:30 > 0:20:34Even though Charlie changed his mind. That's incredible!
0:20:34 > 0:20:36I changed it to orange.
0:20:37 > 0:20:39Are you sure you want to stick with orange?
0:20:39 > 0:20:43Then on the back of the business card, it said "orange".
0:20:43 > 0:20:45The card says, "orange".
0:20:45 > 0:20:46Unbelievable.
0:20:48 > 0:20:51Well, that's inspired me to do some mind reading of my own.
0:20:51 > 0:20:54Pick a number between one and three.
0:20:56 > 0:20:58Your number is...
0:20:58 > 0:21:00four.
0:21:00 > 0:21:02Hmm. Needs a bit of practice, that.
0:21:03 > 0:21:06It's the irrepressible illusionist John.
0:21:06 > 0:21:08Guess what. He's about to go undercover.
0:21:08 > 0:21:12The disguise is on. Come on, mate.
0:21:12 > 0:21:13It's no time for slip-ups.
0:21:13 > 0:21:17Enter Year 4. They don't know it yet,
0:21:17 > 0:21:20but John's about to melt their minds with some magical maths.
0:21:20 > 0:21:22So far, none of them
0:21:22 > 0:21:25has spotted the cameras hidden in the classroom or recognised
0:21:25 > 0:21:29John, but he's about to do a number on them with this mysterious puzzle.
0:21:29 > 0:21:31Good morning, boys and girls.
0:21:31 > 0:21:35We're going to look at number and the relationships of numbers.
0:21:35 > 0:21:39Most numbers can be represented by other numbers.
0:21:39 > 0:21:43For example, the number 12 can be represented by three and four.
0:21:43 > 0:21:453 x 4 = 12.
0:21:45 > 0:21:47We're going to look at a way of representing those numbers
0:21:47 > 0:21:51using a number relationship grid.
0:21:51 > 0:21:54A number relationship grid is also known as a magic square
0:21:54 > 0:21:56and you'll soon see why.
0:21:56 > 0:22:03- I need someone to give me a two-digit number. Yes, Sarah.- 56.
0:22:03 > 0:22:0656, wonderful. We have the number 56.
0:22:06 > 0:22:09That's going to be the number we're going to represent.
0:22:09 > 0:22:12That is our target number.
0:22:12 > 0:22:14Remember number 56.
0:22:14 > 0:22:18Everything's going to come back to that, and it was randomly chosen.
0:22:18 > 0:22:23We need to fill in our relationship grid that represents that number so
0:22:23 > 0:22:2956, the first number in this corner will be 11 because 45 from 56 is 11.
0:22:29 > 0:22:31You don't always take 45 away from the number.
0:22:31 > 0:22:33Depending on what the number is that you start with.
0:22:33 > 0:22:35Once you've got the 11,
0:22:35 > 0:22:38this number here is always two more than the opposite corner number
0:22:38 > 0:22:41- unless that isn't 11. Then, it would be three more.- Eh?!
0:22:41 > 0:22:45Once you've got these two numbers, you can put in a key number.
0:22:45 > 0:22:48The key number is 23. Which is 10 more than 13.
0:22:48 > 0:22:51Once you've got these three, that's the key numbers to the grid.
0:22:51 > 0:22:53You would put a six here which is half of 12,
0:22:53 > 0:22:54which is one less than 11.
0:22:54 > 0:22:55And put in 26 here.
0:22:55 > 0:23:00- Which is three more than 23 which, of course, is half of six.- What?!
0:23:00 > 0:23:02The class is confused. I'm confused.
0:23:02 > 0:23:06You put a 16 over here which is of course 10 less than 26.
0:23:06 > 0:23:08Once you've put the 16 in, you can put seven over here and
0:23:08 > 0:23:1210 here which of course is a natural progression from 13, 11 down to 10.
0:23:12 > 0:23:15You always put 12 below 23 because it's almost half of 23,
0:23:15 > 0:23:17but not quite.
0:23:17 > 0:23:19Once you've got that, you can start working on your bottom line.
0:23:19 > 0:23:23This number is there is always 15. You've got 11, 12, 13.
0:23:23 > 0:23:24There's no 4, 15.
0:23:24 > 0:23:27We never bother about 4, 15. We've all gone home.
0:23:27 > 0:23:28We're eating tea by that time.
0:23:28 > 0:23:32He's just telling jokes now. Those numbers are going in randomly.
0:23:32 > 0:23:35You would get 25 over here.
0:23:35 > 0:23:36Which is two more than 23
0:23:36 > 0:23:40and it moves across in a position like a knight would move in chess.
0:23:40 > 0:23:43Once you've got a 25 over here, you can put the five down here and, in
0:23:43 > 0:23:46the bottom corner, you would have one more than this,
0:23:46 > 0:23:47which of course is 24.
0:23:47 > 0:23:50I think it's becoming much clearer to you now how it works.
0:23:50 > 0:23:53You would then put in your bottom number.
0:23:53 > 0:23:56- Your bottom number's always an 8. - Yeah. Always an 8.
0:23:56 > 0:24:00This number is 14. Then you put your last number which is 9.
0:24:00 > 0:24:03Which is one more than 8, but quite a lot less than 15.
0:24:03 > 0:24:05Hoo-ee! If that's real maths, count me out,
0:24:05 > 0:24:09but the magic's coming and John is going to make sense of it all.
0:24:09 > 0:24:11Obviously, you have to test the theory
0:24:11 > 0:24:14and the way to test the theory is like this.
0:24:14 > 0:24:18You've got to add them up in rows to see if they add up to 56.
0:24:18 > 0:24:23For example, 11 + 16 + 5 + 24 = 56.
0:24:23 > 0:24:26We know the grid is working.
0:24:26 > 0:24:306 + 23 + 12 + 15 = 56
0:24:30 > 0:24:3526 + 7 + 14 + 9 = 56
0:24:35 > 0:24:3713 + 10 + 25 + 8 = 56
0:24:37 > 0:24:40I don't have to tell you that. You're ahead of me.
0:24:40 > 0:24:44- All the columns add up to 56. Amazing.- Then we can go horizontal.
0:24:44 > 0:24:4913 + 26 + 6 + 11 = 56
0:24:49 > 0:24:5310 + 7 + 23 + 16 = 56
0:24:53 > 0:24:5825 + 14+ + 12 + 5 + 56
0:24:58 > 0:25:018 + 9 + 15 + 24 = 56
0:25:01 > 0:25:05Whoa! All the rows add up to 56 too!
0:25:05 > 0:25:08The how did he do that? It all seems so random.
0:25:08 > 0:25:10To check there is a correct number relationship grid,
0:25:10 > 0:25:11you must add them up diagonally.
0:25:11 > 0:25:138 + 14 + 23 + 11 = 56
0:25:13 > 0:25:1613 + 7 + 12 + 24 = 56
0:25:16 > 0:25:19Really, if you wanted to check the whole system,
0:25:19 > 0:25:21you've got to do the corner numbers.
0:25:21 > 0:25:2313 in this corner and 11 in this corner which equals 24.
0:25:23 > 0:25:26+ 24 + 8 = 56
0:25:26 > 0:25:30No matter which way he does it, the numbers always add up to 56.
0:25:30 > 0:25:31That's magic.
0:25:31 > 0:25:33What I'd like you to do, on your sheets of paper,
0:25:33 > 0:25:36you've got a grid, in groups of two or three,
0:25:36 > 0:25:40I'd like you to fill in that grid so it all adds up to 95.
0:25:40 > 0:25:42Could you do that now? I'll give you two minutes.
0:25:42 > 0:25:46- Two minutes, thank you very much. - Look at their faces.
0:25:46 > 0:25:49They can't possibly do it.
0:25:49 > 0:25:50John is going to have to let them
0:25:50 > 0:25:53in on a secret soon before they get headaches.
0:25:56 > 0:26:00Can you put your papers down for a moment? Put your papers down.
0:26:00 > 0:26:03I'm very impressed that you are all having a go.
0:26:03 > 0:26:08You might find it quite difficult because I'm not really a teacher.
0:26:08 > 0:26:10I'm actually a magician.
0:26:10 > 0:26:13You've been set up by your teachers and your parents
0:26:13 > 0:26:16and there's a camera at the back and there's a camera over here.
0:26:16 > 0:26:18There's even a camera right over here.
0:26:18 > 0:26:22You're all going to be on CBBC's Help! My Supply Teacher Is Magic.
0:26:22 > 0:26:25CHILDREN: Oh!
0:26:25 > 0:26:30John's magical grid left the class perplexed. Were they impressed?
0:26:30 > 0:26:35When he was speaking, I didn't get what he was saying
0:26:35 > 0:26:37because he was talking very fast.
0:26:37 > 0:26:41The numbers just made me a bit dizzy because it was so fast.
0:26:41 > 0:26:47It was hard to keep up, but John's logic didn't seem to add up.
0:26:47 > 0:26:50When he started adding those numbers so fast,
0:26:50 > 0:26:55- I didn't know what was going on. - I was just amazed.
0:26:55 > 0:27:01From out of the maths mire, John's magic turned every answer to 56.
0:27:01 > 0:27:06- The number the class had chosen. - ..Plus the 8 in the corner is 56.
0:27:06 > 0:27:11An incredible trick, and this class didn't realise.
0:27:17 > 0:27:21That, my friends, was called the magic square,
0:27:21 > 0:27:24a trick that many magicians from the Magic Circle can do.
0:27:24 > 0:27:28I'm starting my own magic group, and it's a magic triangle.
0:27:28 > 0:27:30Why is it magic?
0:27:30 > 0:27:32CLANG!
